The 103 is as good a handling car as you can buy. The 104 is current for TCS racing if that's what you want to do! But for F-1 club racing -- it's as good as it gets!! LOT'S of parts availability still---but tell the LHS owner---it's NOT the current car---so he SHOULD discount it a little. I've been picking these up built but in EXCELLENT condition for around $125.00 ---with ALL the hopups on them!!
